just pass your varchar or datetime variables in dynamic query like :

'''+@date+'''

this will convert your date value to '1-1-2014' and that's the error in your case as you are getting out_date=1-1-2014.

i hope this will help.

sorry for late reply. i was on vacation... :)

As your requirement, you don't need to convert your comma-delimited list to int but convert your column id to nvarchar on the fly.

And as your problem, you can use EXEC() function:

EXEC('select id,name from MyCylenderMaster where id in ('+@ids+')')

OR CHARINDEX() function like:

CHARINDEX(CONVERT(nvarchar,id),@ids,0) > 0
